METHOD AND APPARATUS FOR CONTROLLING STEERING OF AN AUTONOMOUS VEHICLE FOR DRIVING BETWEEN FLOORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18222234 titled 'METHOD AND APPARATUS FOR CONTROLLING STEERING OF AN AUTONOMOUS VEHICLE FOR DRIVING BETWEEN FLOORS
Simplified Explanation: The patent application describes an apparatus that calculates the steering angle of a vehicle based on obstacle information, safe area direction, movement direction, and driving direction information.
- The apparatus includes an obstacle-information acquisition unit to gather information about obstacles on inter-floor connection ramps.
- A safe-area-direction acquisition unit determines a safe area direction vector based on the front area of the vehicle and the obstacle.
- A movement-direction acquisition unit decides the vehicle's movement direction using the safe area direction vector, obstacle information, and driving direction.
- A steering-angle calculation unit then calculates the target steering angle of the vehicle based on the movement direction and the current steering angle.
Key Features and Innovation:
- Acquisition of obstacle information related to inter-floor connection ramps.
- Determination of a safe area direction vector based on the front area of the vehicle.
- Calculation of the target steering angle considering the movement direction and current steering angle.
Potential Applications: This technology can be applied in autonomous vehicles, parking assistance systems, and obstacle avoidance systems.
Problems Solved: The technology addresses the challenge of efficiently calculating the steering angle of a vehicle based on obstacle information and safe area direction.
Benefits:
- Improved safety in navigating obstacles.
- Enhanced efficiency in steering angle calculations.
- Better maneuverability in tight spaces.
Commercial Applications: Potential commercial applications include autonomous vehicles, self-parking systems, and advanced driver assistance systems (ADAS).
Questions about Steering Angle Calculation: 1. How does the apparatus acquire obstacle information related to inter-floor connection ramps? 2. What factors determine the safe area direction vector in the calculation of the target steering angle?
Original Abstract Submitted
An apparatus calculates a steering angle of a vehicle and includes: an obstacle-information acquisition unit configured to acquire obstacle information related to an obstacle of an inter-floor connection ramp within an area of interest of the vehicle; a safe-area-direction acquisition unit configured to acquire a front area having a predetermined width in a width direction and a length as long as a length of an area in contact with the obstacle in a longitudinal direction with respect to a center point of a front end of the vehicle, and to acquire a safe area direction vector heading from the center point of the front end towards an end of the front area; a movement-direction acquisition unit configured to determine a movement direction of the vehicle according to the safe area direction vector, the obstacle information, and driving direction information depending on a current steering angle of the vehicle; and a steering-angle calculation unit configured to calculate a target steering angle of the vehicle based on the movement direction and the current steering angle.
